It was hiding inside a copy of The Advancement of Learning and Novum Organum, by Francis Bacon. I’m not familiar with the contents honestly? Still. It’s heartwarming getting to see this very human thing and interesting to wonder why it was stuck here of all places.
Seeing this made me miss a subreddit I used to subscribe to called r/forgottenbookmarks.
That would be a great community to revive here :)
Together with r/foundpaper! :>
